com.googlecode.objectify.cache.TriggerSuccessFuture<T>

All Implemented Interfaces:

Future<T>

extends TriggerFuture<T>

Extends TriggerFuture so that it only gets triggered on successful (no exception) completion of the Future. This prevents, for example, cache put()s from firing when concurrency exceptions are thrown.
